of the element e.

In assembling the parts: the spring p,

sleeve m and flexible element 2' are placed, within the boss; 6 of'fthe portion a'above mentioned, and over the exterior of the boss a hollow knob 9 (Figures 5 and 6) is placed, this being then se'curedto said sleeve and flexible .element by a central rivet 1 which is preferably formed integrally with the knob and passes through the holes in the ends of One end of the spring abuts against the shoulderat the outer end of the sleeve as already stated.

'The other end abuts against theflange Ci of the body part a. Due to the endwise pressure of the spring on the sleeve the free end of the flexible element is pressed against the conical or like portion f of the 'bosse on the plate d secured to the part a, and the said end of the flexible. element is thereby contracted. A pull applied to the outer knob causes the sleeve and the flex ible element to be moved axially against thespring and by withdrawing the flexible element from the rigid-surrounding conical boss with which it co-operates :permitsthe tree-end of the flexible element to expand.

The other part of the fastening comprises a spherical, grooved, shouldered or other head .9 over which the above described 7 flexible or contractible gripping element 2' can pass, the head being secured to the part on which it is mounted by a screwstem t or other suitable means. a V

2. In a fastening as claimed ill-cla m 1,.

the combination with the 'contractib' le and 5 axiallymovable element, of asleeve, said spring being mounted on-and cooperating with the sleeve, and said external means for actuating said element consisting of a knob arranged to also actuate said sleeve.

8; In a fastening asclaimed in claim 1, r

the combination with the contractible and axially movableelement, of a sleeve,"said spring being mounted on and cooperating the combination slightly resilient with the sleeve, and said external means for actuating said element consisting of a knob arranged to actuate said sleeve and to enclose the boss of said disk.

4. A fastening as claimed in claim 1 in which the external means for actuating said element consists of a knob having an inter nal rivet secured to, the contractible and axially movable element.

5. In a fastening as claimed in claim 1, with the body part, of a washer, and an expansible eyelet having one end adapted to be secured between said body part and washer.

6. In a fastening of the type specified, the combination comprising a body part consisting of a pair of components each of which is in the form of a disc or plate having a boss on one side, the boss of one component being provided with an internal flange, and the boss of the other with aconical seating piece, a contractible and axially movable gripping piece having a bulbous enlargement at its flexible end adapted to co-operate with the said seating, a flanged sleeve surrounding said element, a spring located between the flange on the sleeve and the flange on one of the body components, an external hollow knob formed integrally with a rivet for connection with the said axially movable element, said knob being adapted to enclose the boss on one of the body components, a resilient washer secured to one side of the disc portion of the body part, an expansible eyelet having one end adapted to be secured between the said body part and washer, and complementary member of the fastening adapted to be detachably secured to the other by engagement with the said contractible and axially movable element, substantially as described.

In testimony whereof I have signed my name to this specification.
